Summary

Ultrasound-guided quadratus lumborum block (QLB) is a fascial plane block where local anesthetic is injected adjacent to the quadratus lumborum muscle with the goal of anesthetizing the thoracolumbar nerves.

In TLIP block, local anesthetic solution is injected between the multifidus and logissimus muscles nearly at the level of the 3rd lumbar vertebra and targets the dorsal rami of the thoracolumbar nerves. Ahiskalioglu et al. defined modified-lateral technique of TLIP (mTLIP) block as a new approach. Ahiskalioglu et al. have reported that this approach has some advantages. Firstly, sonographic visualisation is more easily than the classical technique. Secondly, insertion of the needle from medial to lateral direction reduces the risk of possible neuraxial injection. It has been reported that this technique provides effective analgesia after lumbar spinal surgery.

The aim of this study is to compare US-guided mTLIP block and QLB for postoperative analgesia management after lumbar disc herniation-laminectomy surgery.

Conditions

  • Lumbar Disc Herniation

Interventions

OTHER

Quadratus Lumborum Block

The block procedure will be applied after the surgery and before extubation with patients in the prone position by using US (Vivid Q, GE Healthcare, US). Under aseptic conditions, the probe will be covered with a sterile sheath and a 22G, 80 mm block needle (Braun Stimuplex Ultra 360, Germany) will be used. After visualizing the abdominal muscles, the needle will be punctured and 5 ml of saline will be injected into the postero-lateral border of the quadratus lumborum muscle. After the block location is confirmed, 15 ml of 0.25% bupivacaine will be injected. The same process will be applied to the opposite side (30 ml totally).

OTHER

Modified-thoracolumbar interfascial plane block

US probe will be placed vertically at the L3 vertebrae level. After visualizing the hyperechoic shadow of the spinous process and interspinous muscles as an anatomical guide point, the probe will be moved forward to the lateral to visualize the longissimus and iliocostal muscles. Between these muscles, block needle will be inserted within in plane technique in a medial-to-lateral direction in the interfascial plane. Once the needle tip will be placed within the interfacial plane and after careful aspiration to rule out intravascular needle placement, 2 mL of saline will be injected to confirm the proper injection site, and then a dose of 0.25% bupivacaine 15 mL will be injected in each side (30 ml totally).
